fix(tests): add Django 1.2 and 1.3 to tox.ini

This fix simply adds the testing configuration for Django 1.2 and 1.3
and removes the tox configuration for python2.5 as that is no longer
supported since v3.1.

The extra command for Django 1.2 simply cleans up the temporary database
created by the testsuite in Django 1.2.
